Helena, 17, was on the first floor of the school when the shooting began.

According to friends, the teen told a classmate to grab several books to shield herself from the gunman.

Helena died and her friend was hurt, but survived.

Helena's death was announced by a family member who remembered her in a Facebook post by writing, "Though she was somewhat reserved, she had a relentless motivation towards her academic studies, and her soft warm demeanor brought the best out in all who knew her. She was so brilliant and witty, and I'm still wrestling with the idea that she is actually gone."

Broward County Public Schools Superintendent Robert Runcie was among the many other loved ones who attended Helena's funeral.
